Application filed imgu'st 16,

My invention relates to a ibrooder and particularly to the. means for applying fresh air to the chick chamber and ventilating the same, as wella-sto themeams for indirectly heating said chamber.

The general object of my invention is to provide a brooder in which ample fresh air will be supplied .at all times and in which the heating means employed beneath the brooder cannot a'esultin undesirable heating of the chick chamber or injury to the chicks.

The nature of my invention and its distinguishing features and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming a part of this specification, it being understood that the drawings are merely illustrative of one example of the invention.

Figure 1 is a perspective view of a brooder embodying my invention;

Figure 2 is a longitudinal vertical section without the runway for the chicks;

Figure 3 is a plan view of the brooder without the runway, and with the cover removed;

Figure 4 is a horizontal section on the line 4-4 of Figure 2.

In carrying out my invention in accordance with the illustrated example, a structure 10 forming the brooder body has double walls to form an air space 11 extending at the sides, ends and bottom of the body 10, see Figures 2 and 4. Beneath the brooder body 10 and shown as supporting the same is a base structure 12 adapted to accommodate a source of heat as for example a lamp 13. Above the lamp 13 and beneath the bottom of the brooder body 10 a heat spreader-1 1 is provided held in place in any suitable manner. A ventilator 15 of known form is provided on the removable cover 16 of the brooder body 10 which cover is usually sloping.

In the opposite ends of the brooder body 10 and extending through the double walls thereof are air inlets 17 controlled by slide covers 18. The heat chamber or base 12 has an air inlet opening 19 controlled by a cover 20 having holes 21 for a restricted supply of air to said chamber. In addition to the air inlets 17 extending directly to the brooder chamber 22 through the double walls of the body 10, I provide an air inlet 23 leading to the space 11 and controlled by a slide cover 1m. Serial Io. .IUM'L 24. In the inner one of the :double Wal is air holes 25 are formed atf-the ends and :back and-so located and in suflicient number as to afford ample inlet .for air from the space 11 to the interior brooder chamber 22. Thus, fresh air is supplied from the inlet 23 through the .air holes 25 to the brooder chamber. In addition to the main ventilator 1,5 I provide ventilating openings 26 in the cover 16 at the corners of the brooder, there being fixed-covers 27 :over said ventilating openings 26. Y

Within the brooder chamber 22 at the corners, I provide vertical air baflles 28 which form triangular vertical air passages 29 in the corners of the brooder chamber 22. The lower ends of the baffles 28 are above the bottom of the brooder chamber 22 and said baffles terminate at the up or ends slightly short of the cover or r00 16. The result is that much of the air passing into the brooder chamber 22 through the inlets 17 and air inlet holes 25, will be induced to take an indirect passage to and upwardly through the vertical air passages 29, whereby fresh air will be continually and effectively disseminated throughout the brooder chamber before the air finally passes to the ventilator 15 and air vent holes 26. The double bottom of the brooder chamber prevents the direct heating of the bottom of the chamber and protects the chicks. At the same time the double bottom wall serves to heat the air before it enters the chamber 22 and in this connection it is to be noted that the inlet hole 23' and the air inlet holes 25 are near the bottom of the brooder chamber. The air inlets 17 leading directly to the chamber 22 also are positioned in the ends of the brooder body 10 adjacent to the bottom thereof where the greatest heat is present.

A run structure 30 is employed in practice at an end of the brooder body 10 so that the chicks may freely pass through the adjacent opening 17 to and from said run 30. An

opening 31 is provided in practice at the end of run 30 and controlled by a closure slide 32 so that the chicks may be permitted to escape from the run 30 when desired.

I would state furthermore that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein illustrated, since, manifestly, the same can be considerably varied without departure from the spirit of the invention as defined in the appended claims.

Having thus described my invention, I claim: I

1. In a brooder, a body forming a brooder chamber and having double walls at the sides and bottom, a source of heat beneath the bottom, an air inlet leading through the double Walls to said brooder chamber, an air inlet leading'to the space between the Walls, the inner Wall. having air inlets to permit air from said space and the said second inlet to enter the brooder chamber, said firstmentioned air inlet and said second-n'1entioned inlets being adjacent to the bottom of the brooder chamber. said brooder chamber having vents near the corners at the top of the brooder, and battles forming vertical passages adjacent said vents, the lower ends of said baflies being above the bottom oi. the brooder chamber.

2. In a brooder, a body forming a brooder chamber and having double walls at sides thereof and at the bottom, means supporting said brooder body elevated to accommodate a. source of heat beneath the same, an air inlet leading through the double Walls to said brooder chamber, an

air inlet leading to the space between the Walls, theinnerwall having air inlets to permit air from said space and the second inlet to enter the brooder chamber, said first-mentioned air inlet and said last-mentioned air inlets being adjacent the bottom of the brooder chamber, said brooder body having vent means at the top; together with IRVING MEAD,
